Frequently Asked Questions
About Thumba
What is Thumba all about?
Thumba is an enterprise AI platform that converts requirements, user stories, workflows, and project documents into high-quality user stories, acceptance criteria, and test cases, while identifying gaps that cause rework and go-live delays.
Who are the ideal users of Thumba?
Thumba is designed for teams involved in planning, building, and validating software delivery, including Product Managers, Business Analysts, Quality Analysts, Scrum Masters, and Engineering Managers. Each role uses Thumba to reduce ambiguity, eliminate rework, and ensure sprint-ready artefacts before development begins.
Which domain does Thumba address?
Thumba is domain-agnostic and is actively used across regulated and non-regulated industries such as Banking, Insurance, FinTech, Healthcare, Real Estate, Manufacturing, and Software Product companies. The models are designed to respect domain terminology, compliance constraints, and project-specific glossaries.
What are core features of Thumba?
- AI User Story & Acceptance Criteria Generation — Converts requirements, epics, documents, and workflows into structured user stories and acceptance criteria.
- AI Test Scenario & Test Case Generation — Automatically generates test scenarios, test cases, test steps, and expected results for QA teams.
- User Story Gap Detection & Auto-Fix — Scans user stories for ambiguity, inconsistency, missing scenarios, and fixes them using industry standards.
- Workflow & Image-Based Generation— Converts Visio files and workflow images into executable user stories and test cases.
Does Thumba accept project documents such as FSD, PRD, Architecture diagram, etc.?
Yes. Thumba accepts project documents such as BRD, PRD, FSD, architecture diagrams, and supporting artefacts in DOCX and PDF formats. Uploading project artefacts significantly improves context, coverage, and accuracy of generated user stories and test cases.
How accurate is the output from Thumba?
The accuracy of Thumba’s output depends on the quality and completeness of input data. Customers have reported up to 95% accuracy in generated user stories and test cases when project documents and artefacts are included.
Can Thumba store all the project repositories and generated information?
Thumba is built keeping enterprise grade privacy and data protection for all its users. All the artefacts fetched from your source ALM or uploaded documents are NOT STORED in Thumba, similarly all outputs are either downloaded into your local folder or the user can manually submit back to source project in the respective ALM. We retain zero user data or project information except for limited details to connect with your source project. All input and generated data are deleted once user navigates to different page or post their logout. Thumba does not use customer data for model training and follows enterprise-grade security and privacy practices.
Where is Thumba based out of?
Thumba is headquartered in UK, with teams spread across London, Trivandrum and Bangalore.
Thumba vs Generic AI Models
How is Thumba different from Co-pilot and generic GPTs which can also generate project artefacts?
Unlike generic AI tools, Thumba is purpose-built for software delivery workflows. It combines requirement understanding, industry standards, consistency, and enterprise privacy to deliver predictable, production-ready outputs.

| 2 | Consistency & Scalability | Consistency – 95% (± 5%) Enterprise Adaptive Scaling | User or individual dependent, variable output, non-scalable |
| 3 | Industry Best Standards | Inbuilt industry standards for all generation & scanning | Depends on user knowledge, prompt quality & subscription type |
| 4 | Data Usage and Privacy | Zero data storage. No user data used for training AI models | Can vary based on models |
| 5 | Product Support | Agile, highly personalised & human-in-loop | Large, mostly self-managed |
User Story Validation and Fixing Gaps
Why should I scan user stories for gaps?
Poorly written user stories are a leading cause of sprint rework and delayed go-lives. Thumba scans user stories to identify ambiguity, contradictions, missing scenarios, and inconsistencies before development begins.
Does Thumba fix gaps identified post scanning?
Yes. Thumba identifies gaps in user stories and acceptance criteria, such as ambiguity, missing scenarios, inconsistencies, and incomplete coverage and fixes them using industry best practices and your project documents. This ensures user stories are sprint-ready and require minimal manual review.
Why are some user stories highlighted in yellow after fetching?
When user stories are fetched for scanning, Thumba performs a pre-scan sanity check to identify formation issues, grammatical errors, or unsupported characters. User stories flagged in yellow must be corrected before running the full scan to ensure accurate results.
How should I scan and fix user stories and acceptance criteria?
These are the steps you can perform in scanning:
- Integrate your project — Connect your Jira or Azure DevOps project. If user stories are in Excel, create an Excel-based project.
- Fetch user stories — Navigate to Scanning and fetch user stories and acceptance criteria from the project.
- Review pre-scan checks — Thumba performs a pre-scan to highlight basic issues that must be resolved before full scanning.
- (Optional) Upload project glossary — Upload a glossary to ensure abbreviations and domain terms are interpreted correctly.
- Run full scan — Select the user stories and initiate the full scan.
- Review scan results — View gap reports directly in the UI, export them as Excel, or submit gaps back to Jira or Azure DevOps.
- Upload supporting documents — Upload PRD, BRD, FSD, architecture diagrams, or related artefacts for better context and accuracy.
- Fix gaps using Thumba — Select user stories with gaps and use Fix Gaps(s) to automatically fix them based on project artefacts and industry standards.
- Edit and submit output — Review, edit if required, and download as Excel or submit back to Jira or Azure DevOps.

Why am I unable to view user stories for creating a project?
This can happen for one of the following reasons:
- No user stories exist in Jira or Azure DevOps
- Incorrect column names in the uploaded Excel file
- No action was taken within 30 minutes after fetching (you can re-fetch)
- User stories are already in a Done or Fixed state
Where do I find the fixed user stories and gaps in Jira or Azure DevOps after submission?
Fixed user stories are created as separate linked items in your project. The gap report is attached to each original user story for traceability and future review.
Does it modify my original user story?
No. Thumba creates a new user story with the fixes applied and links it to the original user story. The original item remains unchanged.
Can I upload user stories from an Excel file?
Yes. You can upload user stories from an Excel file, provided the columns are correctly labelled according to Thumba’s supported format.
Can I scan epics, bugs, and tasks too for defects?
Currently, Thumba supports scanning of user stories and acceptance criteria only. Support for additional work item types may be added in future releases.
Generation From Requirements
What is the purpose of generation from requirements?
Generation from requirements enables teams to automatically convert raw requirements into structured delivery artefacts.
Using requirements from Jira, Confluence, Azure DevOps, or uploaded documents, Thumba can generate:
- User stories
- Acceptance criteria (standard and Gherkin formats)
- Test scenarios
- Test cases
This approach significantly reduces manual design effort for Business Analysts and QA teams, with customers reporting up to 85% reduction in design effort and up to 95% accuracy, depending on input quality and context provided.
How can I upload requirements to Thumba?
You can upload or fetch requirements in the following ways:
- Fetch requirements or epics directly from Jira or Confluence
- Fetch requirements from Azure DevOps
- Upload requirements from an Excel file, ensuring the requirement column is clearly labelled.
Why am I unable to generate User Stories from Excel?
Please verify the following:The requirements column is labelled exactly as “requirements”
- The requirements column contains data and is not empty
- The generation process may take a few seconds to several minutes, depending on volume and complexity.
- Do not refresh or navigate away during processing
If the issue persists, contact support at support.thumba@thumba.ai
Why am I unable to generate User Stories from Jira or Azure DevOps?
Use the following checklist to troubleshoot:
- Confirm that Jira or Azure DevOps project details are entered correctly during integration
- Ensure all requirements are present in the project before initiating generation
- Thumba fetches only requirements that are in Backlog or In Progress states
Where can I view the submitted data in Jira?
- User Stories — Newly generated user stories are created within the same Jira project.
- Test Scenarios and Test Cases — Generated test scenarios and test cases are stored in the configured test management tool, such as Zephyr or Xray, for that project.
Generation From User Stories
What is Generation from User Stories?
If you have an existing set of user stories and acceptance criteria in your project, QA teams can generate Test Scenarios and Test Cases with the help of your project artefacts.
